Beit known that I, CHARLES B. DOLGE, a citizen of the United States, and a resident .of lVestpor't, in the county of Fairfield andl State of Connecticut, have inventedcertain new anduseful Improvements iu Embalming- Needles, of which the following is a specification.

Myinvention relates tonewand useful iin-y provenients in embalming-needles ortrocars, such as are used for embalming bodies preparatory to burial.

Itis the object of-my invention to improve upon devices of the above class by'so constructing them as to getimprovedresults by their use; also,to provide a construction which can be more readily and thoroughly cleaned aft-e1' being used; further, to provide an instru ment Y which can readily `be sharpened with ordinary tools by inexperienced persons, and, finally, to provide a specially-shaped rod whereby'said needle can be cleaned.

Upon the accompanying sheet of drawings, forming a part of this 'speciication, similar characters of reference denote like or corresponding parts throughout the several iigu res, and of which y Figure l shows a side elevation of an einbalmingneedle embodying my invention.

.Fig. 2 is an edge view of the construction Fig. 8 is a central vertical horizontal section of Fig. Fig. 4 isasimilar horizontal section of Fig. l. Figs. 5 and G show detail. cross-sectional views on lines andG60fFig-l. The needle illustrated in the drawings is a short size; but it will of course be obvious that the length of the instrument is not material and that my improvement is equally applicable te any of the lengths employed, which in practice range from six to iifteen inches. partly or Wholly of rubber or other suitable material.

Needles of this class after being used are necessarily thoroughly cleaned, and for this purpose al wire cleaning-rod is us'ually employed. In practice this rod is inserted int shown in Fig. 1.

My invention may also be made *ii-TENT OFFICE. i'

Referring to the charac marked upon the drawings-f barrel of the 11eedle,\vl1icll1 ,as tains a uniform longitud'i l C indicates ahub, by me l `sofwl l" stru ment is preferably tedf,andv this hub, as shown, maybe-parti lily-Qr-'ehtrely knurled, if desired, to Lvfacilitate; handling.

The forward end of the instrument'is sharpened, having four beveled ilat surfaces P tapered to'a tip G, the Whole producing a spearshaped point, as shown. The top and bottom cutting edges of my instrument, which are formed by the outer intersection of the beveled sides, are finished off even with the surface of the barrel at H. A point of this character comprising fiat surfaces can be more readily and accurately inserted than an instrument Whose point consists of a single bevel extending from side to side or one having what may be termed an arrow-point.

The removal of a large or Wide-pointed needle is likewise more difficult, ,and it is also true that a needle having concaved sides has necessarily got to be sharpened by a special convex tool, While'my instrument may be sharpened with an ordinary iile or oil-stone.

The eye I is a special feature of my invention. (See Figs.y l and i.) As will be seen,

it is of an oval contour and intersects with the barrel of the instrument. The forward end or wall of this eye Icontains a speciallyconstructed web or rib J, which extends diametrically across the axial line of the cylindrical body. The advantage of this construe tion is several fold. First, as stated with regard to the finish of theexterior of the point, it permits of more readily withdrawing the instrument from a body, and, in the second place, it prevents the lodging Within the eye of objectionable matter, which would necessarily be present were the inner wall of the forward end of the eye fiat, concave, or any other shape. It also provides for more readily cleaning the needle, since a wire r'od K, such as I have shown in Fig. 4, with a bend O near its point, canbe inserted in a manner to nicely scrape olf the diverging side Walls M of the eye, as will be apparent from the illustration,

whereas if the eye were of the old shape a straight rod could not be made to give the saine results.

Having' thus described my invention, what I claim as new, and desire to secure by Letters Patent, is i 1. An embalming-needle of the class described, the sa'me comprising a cylindrical body having asuitable point, an eye through said point intersecting the bore of saidbarrel, a rib extending diametrically across the axial line of said body, and beveled off totinish with the surface of said eye and point.

2, An embalmingmeedle of the class described, the saine comprising a cylindrical body having;r a suitable point, an eye through said point intersecting the bore of said barrel, a rib extending diametrically across the I' axial line of said body and beveled od to nv ish with vthe surface of said eye and point,- a rod having a bent point Within said barrel for cleaning the eye, substantially as shown 3. In an einbalmingfneedle of the class described, the combination with a cylindrical barrel having a central bore therein, of a spear-shaped point with dat beveled sides and a cutting edge which does not project beyond the periphery of the barrel, an eye through said point having a central rib diametrically across its forward wall, the 'sides of said rib being beveled off -to finish with said eye and point. l

4. In an embalming-necdle of the class described, the combination with a cylindrical barrel having a central bore therein and a .fiat-sided hub, of a spear-shaped point with fiat beveled sides and a cutting edge which does not project beyond the periphery of the barrel, an eye through said point havinga central rib diametrically across its forward end, the sides of said rib being beveled olf to finish with said eye and point, substantially as shown. v

5. In an embalming-necdle of the class described, the combination with a barrel having a bore therethrough, a series ofannular threads around its butt-end,- a series of elongated orifices arranged irregularly in said barrel, a diamond-shaped point the sidesof which are flat and finished off even with the surface of the barrel, an eye in said needle -provided with a concave rib extending diametrically-across its forward end, a bent rod to engage the side Walls of said rib, substantially as'shown and described. i
